初めまして、どうしても解決できない問題
がありましてMLに参加させていただきました
１月くらいよりmysql.logに

Number of processes running now: 0
050321 19:45:42  mysqld restarted
/usr/libexec/mysqld: ready for connections
mysqld got signal 11;

key_buffer_size=16773120
record_buffer=131072
sort_buffer=524280
max_used_connections=2
max_connections=100
threads_connected=3
It is possible that mysqld could use up to 
key_buffer_size + (record_buffer + sort_buffer)*max_connections = 80379 K
bytes of memory
Hope that's ok, if not, decrease some variables in the equation

Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...
Stack range sanity check OK, backtrace follows:
0x80d6d67
0x4004a194
0x40188c28
0x40188995
0x80e8938
0x80f497d
0x80f8049
0x80f0a46
0x80dd62d
0x80e0a45
0x80dc93c
0x80dbef8
Stack trace seems successful - bottom reached
Please read http://www.mysql.com/doc/U/s/Using_stack_trace.html and follow instructions on how to resolve the stack trace. Resolved
stack trace is much more helpful in diagnosing the problem, so please do 
resolve it
Trying to get some variables.
Some pointers may be invalid and cause the dump to abort...
thd->query at 0x84c2180 = select cid, title, url
		from `main_dsp`,`count_dsp` where `main_dsp`.id=`count_dsp`.cid 
		and genre=3 
		order by incount desc,outcount desc
thd->thread_id=4

となりサービスが落ちてしまう現象が発生しております、落ちることは頻発では
ないですが多いときは１日２、３度あります。また最近どんどん頻度が多くなって
きました。同様の環境が２台ありまして同時期に発生し状況も同様です
環境は　TLS8S + MYSQL3.23.58  X86です、同様の事象を解決例などございましたらお教え願いたくお願い申し上げます。
